Application September 11, 1952, Serial No. Stfifid'i 3 Claims. (Cl. 4-4.16)

The present invention pertains to improvements in female urinals andmore specifically to the provision of vent means therefor.

In the construction of female urinals it is common practice to providethe receptor with a spout-like extension terminating in a portion shapedclosely to conform to the contours of the pubic region of the femaleanatomy. in use, this terminal portion is placed over the genitourinaryorgans and pressed firmly against the body. Thus, an effective seal isformed with the mouth of the urinal spout preventing the escape of airwhich must be displaced from the receptor as the urine is dischargedthereinto. On the other hand, if the urinal is not tightly pressedagainst the users body, there is danger of undesirable leakage aroundthe mouth of the spout.

The invention, basically, resides in the provision in a female urinal ofa specially designed Vent tube which will permit the escape of displacedair but will prevent the spillage of the contents of the urinal.

Therefore, it is a basic object of this invention to provide a femaleurinal comprising means for venting same.

It is a further object to provide a vent for female urinals which willpermit the escape of displaced air therefrom but which will not allowspillage of urine even when the urinal is carried in the normal uprightposition.

it is a still further object to provide a vent for female urinals whichwill allow the emptying of the receptor without spillage of urinethrough the vent.

It is a further object to provide a vent for female urinals which issimple, easily cleaned, has no moving parts and can be easily providedin the construction of con ventional urinals without substantialincrease of production cost. I

These, and other objects and advantages of the invention will becomeapparent as the present description of a preferred embodiment is read inconnection with the annexed drawing in which:

Figure 1 is a longitudinal section of the present invention; and

Figure 2 is a cross-section taken on line 22 of Figure 1.

In the drawing, reference numeral designates, generally, a female urinalpreferably constructed of enameled ware, stainless steel, aluminum,glass or any similar mate rial susceptible to hygienic cleansing andsterilization. The urinal comprises a receptor 12 having a flat bottom14 and a domed upper wall 16. A carrying handle 13 is convenientlylocated on and fastened to the upper surface by any suitable means.

The upper wall 16 contains two perforations 20 and 22. The perforation22 communicates with a tapering upwardly inclined spout 24 which isattached to the receptor wall by any suitable method. The spout ends ina headed over terminal portion 26 so curved and proportioned as toaccommodate the female genitalia and closely conform to the contours ofthe pubic region.

Along the inner surface of the domed upper wall 16 of the receptor isprovided a vent tube 28, which conforms and is attached to said surfaceby any suitable means, for example, by soldering, brazing, etc. The end26 of the tube 28 nearest the spout terminates in a sharp reverse bendso that the open end of the tube faces away from the spout. The oppositeend of the tube passes through perforation 22 in the upper wall of thereceptor and terminates in an exterior extension 32, directed away fromthe user, thereby placing the interior of the receptor in communicationwith the atmosphere via tube 28. The perforation 22 through which thevent tube passes is sealed around the tube, for example, by soldering orbrazing, as shown at 34, Figure 1.

The urinal is used in the conventional manner hereinbefore described. Asthe urine passes down the spout and collects in the receptor, the airdisplaced by the rising liquid level escapes via tube 28 and extension32 passing off to the atmosphere in a direction away from the user.Thus, the air trapped in the urinal cannot impede the filling of thereceptor. When the urinal is carried after use it may be tipped up withthe spout portion elevated in order to preclude spilling of thecontents. The vent is so designed and installed that there is nopossibility of spillage through the vent even while the urinal is in thecarrying position, i. e., with the spout end elevated. Furthermore, asthe urinal is tilted forward for disposal of the contents or forcollection of samples, the position assumed by the vent tube remainssuch that no liquid can escape therethrough.

The invention may be embodied in other specific forms without departingfrom the spirit or essential characteristics thereof. The presentembodiment is, therefore, to be considered in all respects asillustrative and not restrictive, the scope of the invention beingindicated by the appended claims rather than by the foregoingdescription, and all changes which come within the meaning and range ofequivalency of the claims are therefore intended to be embraced therein.

What is claimed and desired to be secured by United States LettersPatent is:

l. A female urinal having a receptor, a spout and a vent for permittingthe escape of air from the interior of said receptor, said ventcomprising a tube extending along the inner surface of the upper wall ofsaid receptor, said tube terminating at one end in a reverse curve nearsaid spout, the other end of said tube protruding through said wall tothe exterior of said receptor in a direction away from said spout.

2. A device of the character described comprising a receptor formed of aflat bottom wall and a domed upper wall, an upwardly inclined, taperingspout attached to one end of the receptor and communicating with theinterior thereof, a vent tube having an intermediate portion extendinglongitudinally along the interior surface of said upper wall and havinga first terminal portion extending through said wall to the exterior ofsaid receptor, said tube having a second terminal'portion sharply bentback upon itself so as to face away from said spout.

3. A female urinal comprising a receptor, a spout at one end of saidreceptor communicating with the interior thereof, and a vent tubeextending longitudinally along the upper wall of said receptor andterminating at one end in a sharp reverse curve adjacent the inner endof said spout, the other end of said tube extending through said wall atthe opposite end of the receptor and in a direction away from saidspout.
